 Broadly oval, convex, robust. Dark reddish-brown, sparsely pubes- 

 cent; sides of elytra often darker. Thorax more than twice as wide as 

 long, narrowed in front, apex emarginate; base and sides curved, the lat- 

 ter narrowly margined; disk convex, coarsely and irregularly punctured. 

 Elytra as wide as thorax, tips rounded-truncate; disk of each with ten 

 rows of slightly impressed punctures; intervals with two irregular rows 

 of fine punctures, each bearing a short yellowish hair. Length 3-4 mm.

XIV. MELIGETHES Steph. 1830. (Gr., "honey + rejoice.") 



Small, subdepressed, black or bronzed species, having the labrum 

 nearly concealed ; antennae with an abrupt 3-jointed club ; point of 

 prosternum enlarged, free and overlapping the mesosternum ; elytra 

 truncate at apex, exposing the tip of abdomen. They feed on vari- 

 ous flowers, eating the pollen and nectar. Five species are listed 

 from the United States, two of which have been taken in Indiana. 

 Both have the front tarsi finely toothed and tarsal claws simple.

 tibiae often paler. Thorax twice as wide as long, sides feebly curved, mar- 

 gins narrowly flattened their full length, hind angles obtusely rectangular; 

 surface finely and rather densely punctate. Elytra as in the next species; 

 intervals between the punctures not alutaceous. Length 2-2.5 mm.
